HQLLOW-BLOGK WALL CONSTRUCTION.

Application filed March a1, 1928. scram. 266,145.

My invention relates to a hollow block wall construction. f

In accordance with my invention, a wall is built of assembled hollow blocks, providing a hollow wall-having a central air passage or space, with an air cell in each block.

The arrangement is such that each air passage and each cell is in communication with every other air passage and cell, providing unobstructed communication between them,

and rendering it possible for the proper circulation of air throughout the entire wall.

- The hollow blocks are also constructed for interlocking engagement. They may be assembled to producea Flemish bond, extending over the entire wall, except at the corner, where corner blocks are used, which produce an attractive finish. The corner blocks have passages and cells, which serve to connect the passagesand cells of the blocks in the two walls The wall produced 'is light,

strong, moisture proof, heat insulating to a high degree, cheap, and attractive in appearance.

In the accompanying'drawings, forming a part of this specification, and in which l1ke numerals are employed to designate like parts throughout the same,

Figure 1 is a side elevation of a wall embodyingmy invention, I

Figure 4 is a similar view taken on line 4-4 of Figure 2, t H v Figure 5'is a transverse section taken on line 5-5 of Figure 2, I

Figure 6 is a perspective view of one of the longitudinal blocks, I I

Figure 7 is a similar view of one of'the transverse blocks.

Figure 8 is aperspective view of. one of the corner blocks, 1 Figure 9 is a perspective view of a filler 4.5 block, and 1 Figure 10 is a perspective view of a mod-ified form of filler block.

In the drawings, wherein for the purpose of illustration, is shown a preferred embodiment of my invention, the numerals 10 and 11 designate hollow walls, shown as arranged at a right angle, and constituting a part of a building.

Each wall embodies horizontal layers of longitudinal and transverse blocks. Y Each layerembodies pairs of longitudinal blocks 12, which are hollow and have inner open- 1ngs or cells 13,- extending through its top and'bottom. Each block 12 is provided at 1ts opposite endswith vertical grooves 14. The pairs of longitudinal blocks 12 are transversely spaced, providing a passage 15. Arranged between thepairs of longitudinal blocks 12 are hollow transverse blocks 16. Each transverse block has an inner opening or cell 17, extending through itsjtop and bottom, as shown. Formed uponthe sides of the transverse block 16 are vertical tongues 17 arranged near and spaced from the ends thereof, and are adapted to fit within the grooves 14, whereby the longitudinal and transverse blocks have interlocking engagement. The transverse blocks 16 in one layer extend centrally across the longitudinal blocks 12, in the adjacent layer, and produce a Flemish bond. The opening or cell 17 in the transverse block 16 is in'free communication with the openings or cells 13 in the adjacent pairs of longitudinal blocks 12, and also in free communication with the passages 15 between the pairs of longitudinal blocks. Hence the cells 13 and 17 and the passages 15 are in free communication with each other, and this communication continues from one layer of the blocks to the next layer, both up and down.

The numeral 18 designates a cornerblock, which is" rovided internally with longitudinal we s 19. .The webs 19 are spaced to provide a central longitudinal passage21, corresponding to the passages 15, and outer cells 22, corresponding to the cells 13. This passage and cells extend through the top and bottom of the corner block. At one en the corner block is provided with vertical grooves 23, corresponding to the grooves 14, and adapted to receive the tongues 17 Upon its inner side, the corner block is provided with vertical grooves 24, suitably spaced, for receiving the tongues 17 upon the transverse block. The corner block has a width equal to the length of the transverse block 16 or the combined width of thetwo longitudinal blocks, when assembled in the wall.

The corner block is reversible-and is used in both walls 10 and 11, by suitably inverting the same in one wall.

As clearly shown in Figure 2, the corner block has its longitudinal passage 21 and longitudinal cells 22 in free communication with the corresponding passage and cell in the corner block next below and above it. These passages 21 and cells 22 are in free communication with the cells 17 of the adjacent transverse blocks 16, above and below the corner block, and also in communication with the passages 15 between the adjacent pairs of longitudinal blocks, above and below the same. As clearly shown in Figure 1, the longitudinal corner block 18 extends throughout the entire width of the adjacent transverse corner block 18 and throughout the entire width of the adjacent transverse block 16 and overlaps the adjacent longitudinal blocks 12 and terminates at the next transverse block 16.

In Figure 9, I have shown a filler block 25, which is used in the event that the wall is terminated at a door jamb or the like. This filler block may be provided with grooves 26 upon its opposite sides. The filler block is to be arranged transversely of the wall, with one set of grooves receiving the tongues 17 of the transverse block, while the other set of grooves may receive wooden strips, to which a door jamb or the like may be nailed.

In Figure 10, I have shown a second filler block of greater width and this filler block isdesignatedby'the numeral 27. This filler block is preferably hollow and is provided with an inner cell 28. This filler block may be provided upon one side with tongues: 29 to engage within the grooves 14 of the longitudinal blocks, and the opposite side of the filler block has vertical grooves 30, adapted to receive strips of wood or the like, to which a door jamb or the like may be nailed.

In assembling the blocks in producing each wall 10 and 11, the blocks are arranged in horizontal layers. The pairs of longitudinal blocks 12 are transversely spaced,,providing the longitudinal passages 15 therebetween. The transverse blocks 16 are arranged between the adjacent ends of the pairs of longitudinal blocks 12, producing a Flemish bond, the transverse blocks in one pair being arranged at the center of the longitudinal blocks of the next layer. The tongues carried by the transverse blocks enter the grooves at the ends of the longitudinal blocks, effecting an interlocking engagement, and the blocks are also held together by mortar suitably arranged between them. Mortar is also arranged between the edges of the layers of the blocks. The corner blocks 18 extend longitudinally in alternate layers in each wall 10 and 11, and transversely in the remaining alternate layers.

The transverse blocks 16 have their cells 17 in free communication with the passages 15 between the pairs of longitudinal blocks 12, and also in free communication with the cells 13 of the longitudinal blocks. As above stated, the passage 21 and cells 22 of each corner block are in free communication with the corresponding passage and cells of the adjacent corner block. Each corner block, extending longitudinally in each wall, also has its passage and cells in free communication with the cells 17 of the adjacent transverse blocks 16, above and below, and its passage 21 in free communication with the passages 15 between the adjacent pairs of longitudinal blocks 12, above and below.

In this manner the corner blocks serve to connect the passages and cells of the blocks constituting the two walls 10 and 11.

It is to be understood that the form of my invention, herewith shown and described, is

to be taken as a preferred example of the each wall embodying horizontal layers of hollow blocks, the blocks in each layer comprising pairs of spaced longitudinal hollow blocks, each longitudinal hollow, block havmg a continuous cell extending throughout the major portion of its length and passing through the top and the bottom of the same, and transverse blocks disposed betweenthe ends of the longitudinal blocks and having interlocking engagement therewith, each transverse block having a continuous cell 1 extending throughout the major portion of its length and passing through its top and bottom, the transverse blocks in one layer beingvdisposed generally centrally of the longitudinal blocks in the next layer and having their cells in free communication with the cells of such longitudinal blocks and also in free'communication with the passage between the longitudinal blocks, and hollow corner blocks arranged alternately longitudinally and transversely in each wall at the end thereof, each corner block having a pair of spaced longitudinal webs providing a central passage and cells upon opposite sides of the central passage, the cells and passage being continuous and extending throughoutthe major portion of the length of the corner block, the corner blocks in the two walls being positioned at generally a right angle in relation to each other and overlapping whereby their passages and cellsare in free communication, the longitudinal corner blocks in each wall extending across the adjacent transverse blocks whereby their cells and passages are in free communication with the continuous cells of the transverse blocks and also overlapping the ends of the adjacent longitudinal blocks, the passages of the longitudinal corner blocks being in communication with the passages between the adjacent pairs of longitudinal blocks, and means for effecting interlocking 101 engagement between each corner block and the adjacent blocks. in the same layer.

In testimony whereof I affix my signature.
